Application filed May 23, 1907. Serial No. 375,229.

To all whom it may concern:

Be it known that I, EARL Gr. WA'rRoUs, a

citizen of the United States, residing at Chi.

cago, Cook county, Illinois, have invented certain new and usefulImprovements in ater-Closets, of which the following is a specification.

My invention relates to water closets particularly designed for use onrailway cars and the object thereof is to provide a simple and efficientcloset of this character and one in which are combined the advantageousfeatures of the flushing and the pan closet, the flushing thereof beingperformed by water under pressure supplied, at will, through the mediumof aslow-closing valve device. Moreover my water closet, in the presentinstance and by preference, is provided with means whereby the pan maybe rendered inoperative and be swung away from operative position withrespect tothe bowl outlet, which arrangement is of ad vantage in theevent that the water supply of the car should become exhausted or theslow-closing valve mechanism should, by chance, become inoperative,whereupon the closet would be converted into an ordinary so called dryhopper closet.

In the drawings Figure 1 is an elevation of my improved water closet;Fig. 2 a plan view thereof with a portion broken away; Fig. 3 a centralsection on the line 3-3 of Fig. 2; Fig. 4 a rear elevation of thewatercloset; and Figs. '5 and 6 detail views of the operating rod orconnection between the pan and operating lever.

The same reference characters refer to the corresponding parts in theseveral figures in the drawings.

Referring to the present embodiment of my invention as shown in thedrawings, the water closet or bowl structure consists of a bowl propermarked 1 having a bottom discharge opening 2 communicating with adischarge space or chamber 3 therebelow formed as an integral part ofthe bowl structure. This bowl structure is arranged to rest upon or besupported by the floor of the car and said discharge chamber 3 isadapted to communicate with the usual discharge pipe or connection (notshown) through the opening or outlet 4 in the base portion of such bowlstructure. The bowl proper is, in the present instance, provided withmeans for a spiral flush and to this end it is provided with a flushingpassage 5 having a discharge port 6 for discharging the water upon theinner surface of the bowl proper at such an angle as to bring about thespiral flushing action in the proper manner and initially at the back ofthe bowl. This water supply passage 5 communicates with the space orchamber 7 formed in the lower part of a slow-closing valve device 8which being not well known and not forming any part per se of my presentinvention, need not be further described, except to say that suchslow-closing valve device which has a top or cap 8 is arranged at therear end of the closet bowl and substantially below the top planethereof, the same being covered by a cap 9 of the same material, usuallyporcelain, as the bowl itself and secured to cap 8 by suitable fasteningmeans such as the screw 9 The pan 10 is arranged below the bowl outlet 2and is of such shape as to contain a body of water suflicient to sealsuch bowl outlet. This pan is arranged to swing downwardly andrearwardly to open the bowl outlet and to discharge its contents and tothis end the pan is pivoted upon a cross rod or shaft 11 extending fromside to side of the bowl structure as shown particularly in Fig. 2.

The slow-closing valve device and pan are arranged to be operated inunison and the same are therefore provided with common actuatingconnections. In the present in stance the operating device is a handleor lever 12 whose inner end has its bearings in the slow-closing valvedevice 8 and is operatively connected with such valve deviceby means ofthe crank arm 13 with the result that when the lever is rockeddownwardly the slow-closing valve device is operated to admit the waterto the passage or chamber 7 and thencethrough the passage 5 and outletport 6 to the interior of the bowl for flushing the same. This move mentof the operating lever is against the tension of the coiled spring 14;which bears at one end against the plate 15 which is pivoted to the lugs16 projecting from the lever 12 and at its other end against therecessed nut 17. For the sake of compactness and simplicity I takeadvantage of the presence of this nut 17 whose primary purpose is toengage the tubular post or sleeve 18 of one of the hinges for the usualcover or lid (not shown) of the water closet. By preference I providethe plate 15 with a connected to a horizontal link 21 whose in- I nerend is in turn pivotally connected with a crank arm 22 secured to therock shaft 11 to which the pan 10 is secured as described. It isdesirable to make provision for adjusting the length of one at least ofthe operating connections in order to compensate for variationsoccurring in the manufacture of the parts so that the pan shall have theproper or desired arc of movement and in the present instance I providesuch adjustment in the link 21 which is made in two parts the rear'oneof which marked23 is formed at its rear end as a hook adapted to hookover or engage a thumb screw 24 which screws into the lower end of thecrank arm 20. As shown particularly in the detailed view, Fig. 6, thestem or shank of the hook 23 is screw threaded so as to screw into therear end of the body of the link 21 whereby the link may be lengthenedor shortened. These parts are held or locked in their adjusted positionby means of a lock nut 25. It will now be understood that when theoperating lever is rocked downwardly in the manner hereinbeforedescribed, the crank arm 20 is rocked rearwardly thereby shifting thelink 21 in the same direction and causing the pan to swing downwardlyand rearwardly. In order to limit the rearward swing of the pan Iprovide the latter with a stop arm 26 which is adapted to engage a partof the bowl structure, the same contacting in the present instance atthe point 27.

For the purpose of convenient access to the discharge chamber 3 belowthe bowl proper and also to the operating parts therewithin I providethe rear end of the bowl structure with an opening of considerable sizewhich is arranged to be closed by a cover 28. In the present instancethis cover, which is in the form of a plate, is provided with aninwardly directed recess 29 whose bottom portion rests upon the top edge30 of the opening in the bowl structure. As a convenient means forlocking the cover or plate in position I provide the thumb screw 31passing angularly through the recessed portion 29 and engaging in frontof the top edge 30 of said opening. As shown in Fig. 1 this plate 28 isprovided with a slot 32 in order to accommodate link 21.

As hereinbefore stated it may become desirable, for instance in case thewater supply on the car should become exhausted, to convert the watercloset into a dry hopper closet, in which event the pan 10 would beswung downwardly .to open position. In order that this may convenientlybe done 1 provide the hook 23 which may be uncou pled from the crank arm20 by simply loosening the thumb screw 24: and I also provide meanswhereby such pan may be held in open position. As shown the lower edgeof the link 21 is provided with a projection or lug 33 which after thedisengagement or the link 21 from the crank arm 20 and after such linkhas been drawn rearwardly, adapted to hook over the bottom of saidslot32 and thereby retain the pan in open position. In order to drain thelower end of the slow-closing valve mechanism of water I provide a pipearranged to communicate with the chamber 3. As shown this pipe is madein two parts or sections, one of. which 34 communicates with the chamberor passage 7 and the other of which 35 is secured to and removable withthe plate or door 28.
